Nearby, a small-scale prototype reactor was being tested. Encased in a transparent dome, the reactor contained a suspended crystal fragment surrounded by the river liquid. Scientists monitored it closely as the liquid reacted with the crystal, creating a steady glow that illuminated the entire setup. The reactor emitted a low, rhythmic hum, its output displayed on a nearby terminal.
"This reactor," another scientist explained as Lucy and Ethel approached, "is a proof of concept. If scaled up, it could generate enough power for an entire colony. And with the liquid's self-regenerating properties, we're looking at a renewable energy source."
Lucy tapped the side of the dome thoughtfully. "So, we've got crystals that act like batteries, liquid that behaves like plasma, and both of them with enough energy to blow up a city if we're not careful. Sounds like we're walking a fine line here."
